Kepler authorizes an unidentified bearer to attend the Steyr Iron Corporation's committee hearing scheduled for 10 September 1628: "Gewalt und Vollmacht der auff 10. Sept. diß 1628ten Jahrs zu Steir angestellten Eisenschen Geselschaffts Commissions Handlung beyzuwohnen". Kepler's signature is set next to his fine papered seal with his initials "I K". - At the hearing, headed by the Upper Austrian civil servants Johann Spindler and Konstantin Grundemann, it was disclosed to the Corporation's several hundred creditors that the Corporation had suffered substantial losses which they would have to bear, so as to prevent a municipal bankruptcy (cf.

F. X. Pritz, Beschreibung und Geschichte der Stadt Steyer [Linz, 1837], p. 276). - Early 20th century pencil note in German on the first leaf ("authorization issued by the astronomer Joh. Kepler. Linz 1628"). Traces of old folds with light browning. Insignificant brownstain at the upper edge. Very finely preserved..
